No matter how long you wait, it will not be approved. I did not receive any related emails. Other projects cannot be approved.
Can I cancel the review of a project currently under review?
No more waiting for approval.
After disabling all advertisements in the app, release it to the store and try to use the advertisement again after getting approval later.
Any problems with this method?
If you are approved in the PlayStore you can show Ads when downloaded from it.
